In the detachable moving-coil structure of theutility model, the moving-coil skeleton and the coiling wire part adopt a detachable structure and adopt a locating step for limiting and a fastener for connection, not only can obtain excellent mechanical intensity, but also is convenient for disassembly, assembly and repair, greatly improves the production efficiency, and lowers the maintenance cost.

Description

A kind of split type moving-coil structure
Technical field
The utility model relates to a kind of vibration testing device, relates in particular to the moving-coil structure in a kind of vibration testing device.
Background technology
So-called vibration test promptly is that the determinand that is opposite on the vibration instrumentation detects with vibration instrumentation imitation vibration environment, to obtain the performance parameter of determinand in vibration environment.
Indispensable parts---moving-coil on the vibration instrumentation as shown in Figure 1, has comprised moving coil framework 1 and winding portion 10.In above-mentioned moving-coil structure, there is not independent reel, described moving coil framework 1 top is the moving-coil table top, the bottom is a winding portion 10, and in order to guarantee higher resonant frequency, usually moving coil framework 1 is become whole with winding portion 10 usefulness curable epoxides.
Though this measure can strengthen the intensity of moving-coil, improve resonant frequency, but coiling belongs to consumable accessory, in case damage then have to destroy the epoxy construction of moving coil framework 1 and winding portion 10, winding portion 10 is decomposed to come out to fix a breakdown again, maintenance cycle is long, expense is high thereby cause, and is unfavorable for that very enterprise increases economic efficiency.
The utility model content
The utility model provides a kind of sound construction and split type moving-coil structure easy to maintenance at the shortcoming of prior art.
Split type moving-coil structure described in the utility model comprises a moving coil framework and a winding portion, and described winding portion also comprises a reel, and described reel is fixedlyed connected by fixture with moving coil framework, and described coiling is wound in the reel bottom.
In the split type moving-coil structure described in the utility model, described moving coil framework is provided with the positioning step of corresponding reel inwall, and this positioning step and reel inwall offset.
In the split type moving-coil structure described in the utility model, described securing member is a fastening bolt, described moving coil framework periphery is provided with a plurality of axially extending bores, described reel top offer vertically with aforementioned moving coil framework on the corresponding screw of through hole, and pass above-mentioned through hole and screw by fastening bolt moving coil framework and reel connected.Perhaps, described moving coil framework periphery is provided with a plurality of radial direction through hole, described reel top radially offer with aforementioned moving coil framework on the corresponding screw of through hole, and pass above-mentioned through hole and screw by fastening bolt moving coil framework and reel connected.
In the split type moving-coil structure described in the utility model, moving coil framework and winding portion adopt split-type structural, and adopt the location to regulate spacing and the securing member connection, not only can obtain excellent mechanical intensity, also be convenient to the dismounting maintenance, improved production efficiency greatly, reduced maintenance cost.
Description of drawings
Fig. 1 is a moving-coil structure cross-sectional schematic of the prior art;
Fig. 2 is a kind of cross-sectional schematic of split type moving-coil structure described in the utility model;
Fig. 3 is the another kind of cross-sectional schematic of split type moving-coil structure described in the utility model.
Embodiment
Be described further described in the utility model below in conjunction with accompanying drawing, so that those of ordinary skills are with reference to implementing according to this behind this instructions.
As shown in Figures 2 and 3, split type moving-coil structure described in the utility model comprises moving coil framework 1 and winding portion 10, described winding portion 10 specifically comprises reel 3 and is wound in the coiling 4 of reel bottom, and described reel 3 and moving coil framework 1 are fixedlyed connected by fixture.Moving coil framework 1 is whole connected mode with winding portion 10 curable epoxides in the moving-coil structural change prior art described in the utility model, and replacing connects with fixture, is convenient to actual maintenance dismounting more.
For making the dismounting and guarantee strength of joint flexibly of moving coil framework 1 and winding portion 10, be arranged to the periphery of moving coil framework 1 step-like in the utility model, the external diameter of this positioning step 5 matches with the internal diameter of reel 3, like this, when moving coil framework 1 is connected with reel 3, positioning step 5 parts of moving coil framework 1 can snap in reel 3, and the lateral surface of positioning step 5 and the inwall 9 of reel 3 are offseted, and can realize the relative positioning between moving coil framework 1 and the reel 3.
As shown in Figure 2, on the basis of above-mentioned employing positioning step, also a plurality of axial through holes 7 can be set, offer the corresponding screw 8 of through hole 7 on a plurality of and aforementioned moving coil framework 1 at the top of reel 3 vertically at the periphery 6 of moving coil framework 1.Described securing member 2 can be fastening bolt, with through hole 7 and the screw 8 of this fastening bolt via aforementioned axial, and is screwed into screw 8 so that moving coil framework 1 and reel 3 are connected and fixed.
As shown in Figure 3, at securing member 2 is under the situation of fastening bolt, through hole 7 on the moving coil framework 1 and the screw 8 on the reel 3 also have another kind of set-up mode, promptly the periphery 6 at moving coil framework 1 is provided with a plurality of through holes 7 radially, radially offer the corresponding screw 8 of through hole 7 on a plurality of and aforementioned moving coil framework 1 at the top of reel 3, this fastening bolt via aforementioned radial direction through hole 7 and screw 8, and is screwed into screw 8 so that moving coil framework 1 and reel 3 are connected and fixed.
Like this moving-coil structure that is provided with, not only since positioning step and securing member guaranteed that moving coil framework reaches with the good location of winding portion and firmly be connected, make simultaneously that also the dismounting of moving-coil is convenient, improved production efficiency greatly.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in instructions and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
